Prevent segfault when the USB product string cannot be retrieved
In the CMSIS-DAP driver, if nothing has been specified by the user, an
attempt is made to find the first device with the (mandatory)
substring "CMSIS-DAP" in any USB device's product string. However,
while (usually) all devices can be traversed, devices the user does
not have permission for cannot be read the product string from,
resulting in a NULL pointer. Trying to find the substring "CMSIS-DAP"
causes a segementation fault then.
This has also been filed as Trac bug #67:
